The 24-year-old left St James’ Park in January on a loan deal, and, in making his 10th appearance of the season for the Nerazzurri against Cesena, reached the 10-game clause in the loan that has made it permanent.
The clause was agreed in the loan so as to guarantee that Santon was at a good level of fitness before signing on a permanent deal, but the transfer has now reportedly all been confirmed.
As per the Chronicle report, the deal has earned Newcastle an estimated £2.8 million windfall, which amounts to almost half the price paid to Inter when Santon was signed in 2011.
Implications for Newcastle?
Despite having made a loss on Santon, to even receive a small fee will help the Magpies replace the Italian international in the summer.
Paul Dummett, Massadio Haidara and Ryan Taylor are all passable, if not brilliant left-backs, and Newcastle would do well to sign a specialised left-sided defender if they are to compete at a respectable level next season.
Although he made 94 appearances for Newcastle, Santon never truly excelled at St James' Park, and his departure will come as no real disappointment to the majority of fans on Tyneside.
